Displaying Shared Interface Information

Purpose

Display information about shared interfaces.

Action

Using the show interfaces so-fpc/pic/slot or show interfaces ge-fpc/pic/slotcommand, display logical interfaces configured on a shared physical interface.

The following fields in the output from the command display information about shared interfaces:

Shared-interface—Located under the Physical interface: section of the output, this field indicates whether the routing domain is the owner or non-owner of the shared interface. If the routing domain is the RSD, the value is Owner. If the routing domain is a PSD under the RSD, the value is Non-owner.
Shared interface—Located under the Logical interface: section of the output, this section includes these fields:
- shared with—(RSD only) Provides the identity of the PSD that owns the shared interface; for example, psd3.
- peer interface—(PSD only) Lists the logical tunnel interface that peers with the logical interface; for example, ut-2/1/0.2.
- tunnel token—Specifies the receive (RX) and transmit (TX) tunnel tokens. For example, Rx: 5.519, Tx: 13.514.

Note: When you issue this command on the PSD for SONET interfaces, the following information about the physical interface is not provided:

Media status
Frame Relay LMI counters
SONET mode

On the RSD (SONET Interface)

In the following sample output, rsd1 is the owner of the physical SONET interface so-7/2/0 and the logical SONET interface so-7/2/0.0 is shared by psd5.
